Spin-state transition in the Fe-pnictides
H. Gretarsson, S. R. Saha, T. Drye +7
We report a Fe Kβx-ray emission spectroscopy study of local magnetic moments in the rare-earth doped iron pnictide Ca_{1-x}RE_xFe_2As_2 (RE=La, Pr, and Nd). In all samples studied…
Hard X-ray Spectrographs with Resolution Beyond 100 micro-eV
Yuri Shvyd'ko, Stanislav Stoupin, Kiran Mundboth +1
Spectrographs take snapshots of photon spectra with array detectors by dispersing photons of different energies into distinct directions and spacial locations. Spectrographs requir…
Crystal field splitting and correlation effect on the electronic structure of A2IrO3
H. Gretarsson, J. P. Clancy, X. Liu +16
The electronic structure of the honeycomb lattice iridates Na2IrO3 and Li2IrO3 has been investigated using resonant inelastic x-ray scattering (RIXS). Crystal-field split d-d excit…
Testing the validity of the strong spin-orbit-coupling limit for octahedrally coordinated iridates in a model system SrCuIrO
X. Liu, Vamshi M. Katukuri, L. Hozoi +12
The electronic structure of SrCuIrO, a model system for the 5d Ir ion in an octahedral environment, is studied through a combination of resonant inelastic x-ray scattering…
Giant Magnon Gap in Bilayer Iridate Sr3Ir2O7: Enhanced Pseudo-dipolar Interactions Near the Mott Transition
Jungho Kim, A. H. Said, D. Casa +7
Using resonant inelastic x-ray scattering, we observe in the bilayer iridate Sr3Ir2O7, a spin-orbit coupling driven magnetic insulator with a small charge gap, a magnon gap of ~92…
Dimensionality Driven Spin-Flop Transition in Layered Iridates
J. W. Kim, Y. Choi, Jungho Kim +6
Using resonant x-ray diffraction, we observe an easy c-axis collinear antiferromagnetic structure for the bilayer SrIrO, a significant contrast to the single layer Sr$_…
